No sorry, your wrong with that last part. I'm 19, and if my parents said no it means NO. If I were to push it, I'd not only have my butt busted, I'd be grounded.
I think it's ungreatful to beg for some thing that costs so much. Not only does it cost a lot, but it is an inconveniance to the whole family.
How dare you insinuate that I am ungrateful. I am grateful for everything I have in life- my family isn't rich, and I know how hard they work to pay for everything they get for us, and I know that a luxury like horses puts a strain on the budget. I live it and breathe it every single day of my life, especially at school, when I work my butt off in order to make my parents proud. I am extremely grateful, and I know that I could not be riding horses.
Because there was a point in my life, not long ago, where I wasn't riding horses. I couldn't even see them. I borrowed every single non-fiction book my local library had on horses, and read them all front to back, and probably most of the fiction ones as well. I asked my parents- politely- if I could maybe go on a trail ride.
So you know what I did? I wrote letters to my parents. I asked them. I explained my reasoning, and left the room frustrated many times.
And I never gave up. Eventually, I got to go to a horse camp once a summer- five or six days of riding a year. And I was so happy.
But, you know what? Five or six days wasn't enough. Not by a long shot. So it was trail rides on special occasions. And then, after much searching, and more persuasion, I got lessons every other week. It was a LOT of riding for me, something I thought I'd never have.
Then, the lessons went from every other week to every week.
This June, I showed the grades I had worked hard for to my parents- and I got to lease. The entire summer.
A show in June, and one coming up in August. Possibly more to come later.
I wasn't handed riding. I worked tooth and nail to get it, a piece at a time, trying to get my parents to understand- even a little- what I was doing and why, and why I should be doing it.
IF I had accepted no for an answer, I wouldn't be where I am right now.
And no, my parents would not "bust my butt" or ground me just for asking for something I love to do, because they KNOW that I work hard, try my best in school, don't break any rules, and all that stuff. They KNOW I'm grateful for everything I get and more. That's the only reason they're letting me ride- my Dad has said it to me several times, and they expect the best out of me. I give it to them.
It doesn't inconvenience my family, at the end of the day, they like and are proud that they can give me this gift.
That's why I believe in working for what you are passionate about. That's why I believe in persuading, and asking, and doing WHATEVER in order to get to your goal. It's why I don't think you should let one "no", or a thousand "no"s get in the way of your dream. If you want it, ASK FOR IT, the worst they can say is "no"- again, and again, possibly. I found it necessary to ask in order to prove that it wasn't a phase, OP. And if I can do it, you, and nearly anyone, can.
TL;DR: Asking your parents for something has not and never will be a sin.
